E-Rate - Discharge or charge power, in watts, expressed as a multiple of the rated capacity of a cell or battery which is expressed in watt-hours. For example, the E/10 rate for a cell or battery rated at 17.3 watt-hours is 1.73 watts. (This is similar to the method for calculating C-Rate.)
Current Density - The current per unit active area of the surface of an electrode.
Electrolyte - The medium which provides the ion transport mechanism between the positive and negative electrodes of a cell.
Cell - The basic electrochemical unit used to generate or store electrical energy.
RMS Voltage - The range of usable voltage + or - 170 VAC.
Specific Energy - The ratio of the energy output of a cell or battery to its weight (Wh/kg). This term is used interchangeably with gravimetric energy density.
Tolerance in % - Limit for allowable variations for a given quantity, expressed as a percent of the rated value.
